old transam driver, thanks for you reply. there are differences between the two cars. I am no expert, but from looking in period pics. one car has the fuel filler in the tailight panel, with a vent to the left of it. the other has the fuel filler cut into the rear spoiler and trunk, is this the car you drove ? can't post a link ! but i'm sure you know the pictures on the autocourse.ca sight. trois rivieres sept./74 with alain. with deperez at tremblant..71. the restored ? freitas car has the filler on the taillight panel. always a lot of questions with these cars, considering the value they now have.
